DEAN, a 1 citizen of Vthe United States, residing4 at Miami, inthe county of Ottawa/and Statezu' of Oklahoma, hav e invented certain new-andv useful "Improvements in '.Char'gingrDevices', ofwhich'the following is a'specific'ation;

yMy invention relates-to ldevices for chargf zing drill holes in mines 'and quarries with I Q blasting powder, or other explosives,` for thepurpose of blastingoutcoal, ores, Vrocketc., and my object is'to providea simple, inex# r`@pensive and efficient device of this character {.gwhereby said drill f h'olesinay be charged y15 morequickly and at less expensethan here- .tofore.-k .r f Inthe Apresent 'method of' charging drill holese specially those-extending inra hori' zontalor A inclined plane,itis customary to form a sort of cartridge Vof a sizeto enter '"thegholejby--l wrappingpaper Varound* the l blasting powder. This .operation Ytales up the miners? time,'requires an expenditure ofk funds for purchaseofthepa er and results` pini more for. less waste o f'p'ow erwhen'pourfrk vv'ing the same into the paperwrapper. No

lthe operation of illingsaid deviceY withV powder and transferring the same to the 30 `drill hole can lbe .effected in muchless time than is' requiredin forming'the. cartridge above-mentioned.l f A f Inorder that `the inventionfmay be fully understood, reference will vnow beh'ad to the accompanying drawing, in which: Fig. lis a `longitudinal.sectional viewof 'theAVV device .econtainingachar'ge of lpowde and a fusefor exploding'the same. j .Y Fig. 2 is acrosssectio onlineII--IIfof SFglis t' 3 is a detailfperspective view-`of1a 'sa detail perspective view ofthe 'l @receiver and vits handle. l: 1 Fig. V5 .is abroken` detail of -a Vmodified .form Vof'plunger holding 'a fuse.
